摘要: 目的 研究胰腺炎相关蛋白Ⅰ(pancreatitis associated proteinⅠ,PAPⅠ)在急性胰腺炎(acute pancreatitis,AP)动物模型胰腺组织中的表达特点及意义.方法 大鼠轻型胰腺炎(mild acute pancreatitis,MAP)和重型胰腺炎(severe acute pancreatitis,SAP)模型由逆行胰胆管注射1.5%及3.0%牛磺胆酸钠制备.采用反转录聚合酶链反应(RT-PCR)法检测胰腺组织PAPⅠ mRNA的表达,同时检测胰腺组织病理改变、湿/干质量比率、腹水量以评价炎症程度.结果 PAPⅠ mRNA在正常对照组无表达, AP造模后6 h即明显升高, 24 h达高峰,48 h迅速下降.SAP组PAPⅠ mRNA表达水平在6、24、48、72 h各时间点均显著高于MAP组(P<0.05).同时PAPⅠ mRNA表达与胰腺组织病理、胰腺组织湿/干质量比率和腹水量相关.结论 PAPⅠ mRNA的表达变化与AP时胰腺组织损伤程度相关.

Abstract: Objective To investigate the expression of pancreatitis associated protein Ⅰ(PAPⅠ) mRNA in pancreatic tissue in experimental acute pancreatitis(AP).Methods Rat mild acute pancreatitis(MAP) and severe acute pancreatitis(SAP) were induced by retrograde pancreatic duct injection with 1.5% and 3.0% sodium taurocholate respectively.PAPⅠ mRNA was detected by reverse transcription polymerase chain reaction(RT-PCR).Severity of AP was evaluated by pancreatic pathological score,wet/dry weight ratio and amount of ascites.Results The expression of PAPⅠ mRNA could be detected at 6 h,and peaked at 24 h,then dropped rapidly(48()h) after induction of AP.The expression was significantly high in SAP in all time points,compared with MAP.Also,it correlated well with pancreatic pathological score,wet/dry weight ratio and amount of ascites.Conclusion The expression of PAPⅠ mRNA might be related with the severity of AP.
